AI Technical Summary
Technical Problem
Conventional cut-off saws lack effective cooling mechanisms for components such as battery packs, printed circuit boards, and electric motors, especially when cutting heavy materials, leading to potential overheating and reduced performance.
Method used
A cut-off saw design featuring a clamshell housing with partitioned compartments and air intake and outlet openings that facilitate cooling air flow paths around the battery pack and motor, including a direct-drive blade system and an air curtain to manage debris and improve visibility.
Benefits of technology
Enhances cooling efficiency for battery packs, motors, and control electronics, while also providing an air curtain to manage debris and improve user safety and visibility during operation.

Abstract
A cut-off saw housing includes features that define cooling air flow paths through the saw housing that are configured to cool the battery pack, the saw electronics and the saw electric motor. The first cooling path passes through a compartment that houses the battery and cools the battery before exiting the saw housing. The second cooling path passes below the compartment and through a heat sink of a printed circuit board assembly before exiting the saw housing. Both the first and second cooling paths pass through the electric motor before exiting the saw housing.
